Jax got treated after the pshyco cut him. One of the cops told him that they took Jane to the hospital while he was treated and he pleaded the officer treating him to take him to the hospital she was being treated... They took him the day after when he was able to pick her up cause she would be realeased by then. He was fine with that as long as he saw her without any complications.
They told jax it would be better if he waited till she woke up cause her excitement might excel her heart rate.
So He Waited...for a little more...
